I once did a 3d-space representation with https://en.wikipedia.org/wiki/Rhombic_dodecahedron https://en.wikipedia.org/wiki/Rhombic_dodecahedron but in the end it turned out to be easier to just supersample everything down to cube grid, then put some n-vectors on top than to explain everyone how to calculate stuff in that grid. Still have couple dozen ~3" cardboard ones somewhere from when I tried to understand how exactly do they stack. Made a nice lamp when stuffed with LEDs.
